Stage 3 launched more than a week earlier than expected. The clue for the start is apparently buried in an email resulting from the completion of Stage 2.
Jaded Media Experience (JMX) is a puzzle series hosted by JadedMedia.net. The first two stages were tremendously popular, even if certain puzzles were unbelievably frustrating.
If you figure out the start, post it to the Yahoo JMX Spoiler Group. For hints, from into the [Jaded Media Forums].
